CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/552,655, filed on Aug. 31, 2017, which the disclosure of which is hereby incorporated by reference in its entirety for all purposes.

FIELD OF THE INVENTION

The disclosure relates to an autonomous parking system in a motor vehicle.

BACKGROUND OF THE INVENTION

In situations with multiple parking possibilities, an autonomous parking system within a vehicle may not be able to infer which parking space is desired by the driver. Current systems utilize the turn signal switch to indicate only if the driver's desire is to park to the left or the right. These systems do not allow for front, rear or other angles to be indicated.

SUMMARY

The present invention may provide a control switch in a vehicle to indicate the location of a desired parking space to improve the accuracy of an autonomous parking system. The driver may activate the inventive control switch to indicate to the autonomous parking system which parking space is desired.

Optionally, an exterior camera or cameras could be used to identify available parking spaces and highlight the directions of the parking space on the control switch. A display utilizing imaging from vehicle exterior cameras could be used to identify a desired parking location.

The invention may also provide a display-based view of potential parking locations with a touch screen control in a vehicle to enable a driver to indicate and select the location of a desired parking space, thereby improving the accuracy of the autonomous parking system. The driver can utilize a display screen with touch screen control and showing potential parking locations to provide the autonomous parking system with an identification of a desired parking space.

Predefined preferences can also be added to the system such as handicap parking space desirability, acceptable parking space length and width (corresponding to vehicle size), whether the vehicle is towing a trailer to identify an appropriate parking space, first available space versus larger space, etc. The inventive system could also be in communication with cloud-based parking space availability detection systems as those infrastructure systems are installed.

In one embodiment, the invention comprises an autonomous parking arrangement for a motor vehicle, including at least one camera associated with the vehicle and capturing images of parking spaces surrounding the vehicle. An electronic processor is communicatively coupled to the at least one camera and processes the captured images. A touch-sensitive display screen is communicatively coupled to the electronic processor and displays the processed images. The display screen enables a user of the motor vehicle to select a parking space in the processed images by touching the display screen. The display screen indicates to the electronic processor which of the parking spaces has been selected by the user.

In another embodiment, the invention comprises an autonomous parking method for a motor vehicle, including capturing images of parking spaces surrounding the vehicle. The captured images are processed. The processed images are displayed on a touch-sensitive display screen. A user of the motor vehicle is enabled to select a parking space in the processed images by touching the display screen. The motor vehicle is autonomously parked in the parking space that has been selected by the user.

In yet another embodiment, the invention comprises a motor vehicle including at least one camera capturing first images of parking spaces surrounding the vehicle. A touch-sensitive display screen displays second images based on the first images. The second images include a plurality of areas each corresponding to an open parking space in the first images. An autonomous parking system autonomously parks the vehicle in a selected open parking space corresponding to one of the areas on the display screen after the one area has been touched by a user of the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 illustrates one example embodiment of an autonomous parking arrangement 10 of the present invention associated with a vehicle 11. Autonomous parking arrangement 10 includes one or more cameras 12, an electronic processor 14, and a user interface 16. Camera(s) 12 are in bi-directional communication with electronic processor 14, and electronic processor 14 is in bi-directional communication with user interface 16. Camera(s) 12 may capture images of parking spaces surrounding vehicle 11 and transmit the images to processor 14. Processor 14 may process the received images and present parking information to the driver on user interface 16. Processor 14 may also be in bi-directional communication with an autonomous parking system 17.

FIG. 2 illustrates one specific embodiment of user interface 16, including a touch sensitive display screen 18. Displayed on screen 18 are eight touch-sensitive and selectable arrows 20 a-h each pointing in a respective one of eight evenly-spaced directions. In response to the driver touching arrow 20 c, which points in a rightward direction, processor 14 presents an image 22 of the parking spaces to the right of vehicle 11, and the cars disposed in the parking spaces. The presented image 22 may be based on images captured by camera(s) 12. Image 22 may be presented on a same side of display screen 18 as is pointed to by the selected arrow 20. In order to make room for the image 22 on the same side of display screen 18 as is pointed to by the selected arrow 20, the group of arrows 20 a-h may be moved to a side of display screen that is opposite to the direction of the selected arrow 20. Thus, if the driver selects arrow 20 e, the group of arrows 20 a-h may be moved to the top of screen 18 and image 22 may be displayed on the bottom of screen 18. Although screen 18 is shown as rectangular in FIG. 2, it is to be understood that the display screen may have a square shape to provide flexibility in the placement of arrows 20 a-h and image 22.

After the selected arrow 20 has been touched by the driver, autonomous parking system 17 may then autonomously park vehicle 11 in the open parking space to the right of vehicle 11. In one embodiment, after the image of the parking spaces to the right of vehicle 11 is presented on display screen 18, the driver must confirm that he wants to park in the displayed parking space before autonomous parking system 17 autonomously parks vehicle 11. For example, the driver may touch arrow 20 c a second time in order to cause autonomous parking system 17 to autonomously park vehicle 11.

FIG. 3 illustrates another example image that may be presented on display screen 18 and that may be captured by a camera 12 mounted on a dashboard 24 of vehicle 11. The image is of a street 26 that vehicle 11 is traveling on, and includes open or unoccupied parking spaces 28 a-d. After the driver has decided upon one of parking spaces 28 a-d in which to park vehicle 11, the driver may touch the portion of the image on display screen 18 that corresponds to the desired and decided upon parking space. For example, if the driver decides upon parking space 28 b in which to park vehicle 11, then the driver may touch screen 18 at point 30 in order to communicate to processor 14 that the driver would like to park vehicle 11 in parking space 28 b. That is, the touch sensitive screen 18 may detect the touching of screen 18 at point 30, and may inform processor 14 of the touching of screen 18 at point 30. In response to learning that screen 18 has been touched at point 30, processor 14 may cause vehicle 11 to be autonomously parked in parking space 28 b.

In one embodiment, in response to learning that screen 18 has been touched at point 30, processor 14 may highlight parking space 28 b on screen 18 and ask the driver for confirmation that he would like vehicle 11 parked in parking space 28 b. This request for confirmation may be audibly played on loudspeakers within vehicle 11, or presented as text on screen 18. Only after the driver has confirmed that he would like vehicle 11 parked in parking space 28 b, such as orally (as detected by a microphone within vehicle 11) or by further touching of display screen 18, may processor 14 cause vehicle 11 to be autonomously parked in parking space 28 b.

The invention has been described as enabling a user to touch an image on a display screen to indicate a location of a parking space he desires. However, it is also possible within the scope of the invention for the driver to actuate a multi-position switch to indicate a desired parking spot location.

FIG. 4 illustrates one embodiment of an autonomous parking method 400 of the present invention for a motor vehicle. In a first step 402, images of parking spaces surrounding the vehicle are captured. For example, camera(s) 12 may capture images of parking spaces surrounding vehicle 11.

Next, in step 404, the captured images are processed. For example, processor 14 may process the images received from camera(s) 12.

In a next step 406, the processed images may be displayed on a touch-sensitive display screen. For example, the images processed by processor 14 may be displayed on touch sensitive display screen 18.

In step 408, a user of the motor vehicle is enabled to select a parking space in the processed images by touching the display screen. For example, the driver may touch screen 18 at point 30 in order to communicate to processor 14 that the driver would like to park vehicle 11 in parking space 28 b.

In a final step 410, the motor vehicle is autonomously parked in the parking space that has been selected by the user. For example, in response to learning that screen 18 has been touched at point 30, processor 14 may cause vehicle 11 to be autonomously parked in parking space 28 b.
